- * The longest pattern which matches an input string is always chosen.
- * For equal-length patterns, the first occurring in the rules list is chosen.
- * INITIAL is the starting condition, to which all non-conditional rules apply.
- * When in an exclusive condition, only those rules defined for that condition apply.
- *
- * Exclusive states change parsing rules while the state is active.
- * There are exclusive states for quoted strings, extended comments,
- * and to eliminate parsing troubles for numeric strings.
- * Exclusive states:
- * <xb> binary numeric string - thomas 1997-11-16
- * <xc> extended C-style comments - tgl 1997-07-12
- * <xd> delimited identifiers (double-quoted identifiers) - tgl 1997-10-27
- * <xh> hexadecimal numeric string - thomas 1997-11-16
- * <xm> numeric strings with embedded minus sign - tgl 1997-09-05
- * <xq> quoted strings - tgl 1997-07-30
- *
- * The "extended comment" syntax closely resembles allowable operator syntax.
- * So, when in condition <xc>, only strings which would terminate the
- * "extended comment" trigger any action other than "ignore".
- * Be sure to match _any_ candidate comment, including those with appended
- * operator-like symbols. - thomas 1997-07-14
